MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1203 Exploitation for Client Execution
The RTF file contains an embedded OLE object with a PE header, identified by ClamAV as Win.Dropper.Agent-211918. This indicates the file is designed to drop and execute a malicious payload. The embedded object is the primary indicator of malicious intent.
Heuristics 7
-
PE header (with DOS stub) in hex data critical RTF_MZ_HEXHex-encoded PE (MZ + DOS stub) found inside RTF — likely an embedded executable payload
-
ClamAV: Win.Dropper.Agent-211918 critical CLAMAV_DETECTIONClamAV detected this file as malware: Win.Dropper.Agent-211918
-
ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAVClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
-
Package object class high RTF_OBJCLASS_PACKAGEOLE Package object — can wrap arbitrary files
-
OLE object data medium RTF_OBJDATARTF contains 1 \objdata section(s) — embedded OLE objects
-
Embedded OLE object medium RTF_OBJEMBRTF contains \objemb — embedded OLE object
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL http://schemas.microsoft.com/office/word/2003/wordml
